5.7 Exercise 36

A 120-kg astronaut is riding in a rocket sled that is sliding along an inclined plane. The sled has a horizontal component of acceleration of $5.0 \text{m} / \text{s}^{2}$ and a downward component of $3.8 \text{m} / \text{s}^{2}$. Calculate the magnitude of the force on the rider by the sled. (Hint: Remember that gravitational acceleration must be considered.)
